Intelligent Taxiway Guidance System Tested

A new fuel-saving and safety-focused aircraft taxi system is being tested at Frankfurt Airport (EDDF), Germany. The new taxi tool, called “follow the greens,” allows crews to add just enough power to taxi–without intermediate stops–to reach their airport destination. Controllers communicate the go/no-go signals to crews by turning on and off various portions of the airport’s green taxiway centerline lighting, which are also expected to help prevent runway incursions. Constant cockpit throttle positions are expected to save fuel.
